I think it would be a bad thing. I shared a similar question with a friend a couple of years ago, and his answer was that the way humanity is we would most definitely compete in who is better at thinking the same and thus create chaos.
I think we should, instead, learn to accept our differences, understand them, then interlock them a million times over to create something better.

Bridge the gap that makes us constantly torn between forced empathy and selfishness promoted as self-love and care – with conversation, free education and just general engagement with one another that is free of unhealthy restrains put upon us by religion, governments and twisted social standards.
